Stellantis to Launch Semi-Solid-State Battery Fleet

Stellantis plans to introduce a demonstration fleet of Dodge Charger Daytona EVs featuring semi-solid-state batteries by 2026, in partnership with Factorial. This initiative follows Stellantis' $75 million investment in Factorial in 2021 and aims to leverage Factorial's FEST technology, which promises higher energy density, reduced weight, and improved performance over traditional lithium-ion batteries. The STLA Large platform will underpin these vehicles, supporting Stellantis' strategy for high-volume electric SUVs and performance models. While the technology promises significant advancements such as increased range and reduced fire risk, these Dodge Chargers will initially use semi-solid-state batteries, maintaining some liquid electrolytes. The initiative positions Stellantis among the leaders in transitioning to solid-state technology, a challenging field where even companies like Nissan and Fisker have faced setbacks. Factorial's semi-solid-state technology is expected to offer up to 50% more range, aligning with Stellantis' goals of enhancing EV performance and reducing costs.
